Published in 2017 at "STEM CELLS"

DOI: 10.1002/stem.2660

Abstract: Human pluripotent stem cells (hPSC) require signaling provided by fibroblast growth factor (FGF) receptors. This can be initiated by the recombinant FGF2 ligand supplied exogenously, but hPSC further support their niche by secretion of endogenous… read more here.
